I wouldn’t recommend doing it this way. If your new pension fund cannot handle all or part of your voluntary benefits, then the pension fund will transfer that portion to a vested benefits foundation of your choice. You can then choose to invest those benefits with an asset management service, for example. But you are legally obligated to transfer all pillar 2 benefits to your new pension fund first. You may get away with not transferring all your vested benefits, but it could create issues in the future, especially as financial supervision tightens and service providers become more digital and interconnected. It’s best to stick to the rules.
While not being a moderator, I do highly recommend you to stop this discussion about not transferring the 2nd pillar. It was already sufficiently discussed anyway.
